Cardiac contraction affects deep myocardial vessels predominantly

American Journal of Physiology-Heart and Circulatory Physiology, 1991
To evaluate the roles of intramyocardial forces and systolic ventricular pressure in myocardial flow in the different layers separately, we measured myocardial flow in rabbit hearts during stable systolic contracture with left ventricular pressures of 60 (n = 5) and 0 mmHg (n = 5) and during stable diastolic arrest (n = 5). We also measured the number

Myocardial contraction band necrosis in stranded cetaceans

Journal of Comparative Pathology, 1998
The term contraction band necrosis describes focal hypercontraction and lysis of small groups of myocardial cells. Contraction band necrosis of the myocardium was identified in 100% of 52 whales and dolphins (cetaceans) stranded along the western coast of the Gulf of Mexico between April 1991 and November 1996.

Physiology of Myocardial Contraction

2002
The principal function of the heart is to propel oxygenated blood to the peripheral tissues to meet their metabolic demands. The systemic arterial and venous systems provide the conduits. The interaction of the left ventricle (LV) with the arterial and venous systems is therefore integral to the satisfactory performance of this vital function.

[Reversible dysfunction of myocardial contraction].

Vnitrni lekarstvi, 1999
It has been known for more than 20 years that in some patients after revascularization partial or complete improvement of previous left ventricular dysfunction occurs. The condition for this improvement is viable myocardium, i.e. contractile reserve. Chronic reversible contractile dysfunction, also called hibernating myocardium heart muscle is along ...

[Cardiac myosins and myocardial contraction].

Giornale italiano di cardiologia, 1987
The contractile properties of cardiac muscle cells are determined by the molecular composition of the contractile apparatus and in particular by the structure of myosin. Three isoforms of myosin heavy chains have been recently identified in the mammalian heart: alpha and beta myosin heavy chains, present in atrial and ventricular myocardium, and nodal ...

[Myocardial contraction in ischemic heart disease].

Kardiologiia, 1978
The indices of contractility of the left ventricular myocardium were studied by means of ventriculography and catheterization in 84 patients with ischemic heart disease according to the extent of damage to the coronary arteries and the course of the disease.
